Accepted answer
why are you making things complicated
javascript is for clientside validation so simply keep it at clientside
"server" ID="btnSave" Text="Save" CssClass="GreenLightButton"
                       OnClick="BtnSave_Click"
                       OnClientClick="if ( ! SaveConfirmation()) return false;"/>

function SaveConfirmation() {
    return confirm("Are you sure you want to Save Recordr?");
}
just use return in your button click as shown above and done!

"javascript" type="text/javascript">
function validate()
{
      if (document.getElementById("<%=txtName.ClientID%>").value=="")
      {
                 alert("Name Feild can not be blank");
                 document.getElementById("<%=txtName.ClientID%>").focus();
                 return false;
      }
      if(document.getElementById("<%=txtEmail.ClientID %>").value=="")
      {
                 alert("Email id can not be blank");
                document.getElementById("<%=txtEmail.ClientID %>").focus();
                return false;
      }
       SaveConfirmation();


}
function SaveConfirmation() {
return confirm("Are you sure you want to Save Recordr?");
}

but i have not used gridview in my application there is no requirment of gridview to display data.

if you want to print a gridview then its simple.
if you want to send your user to directly send to printer settings of their machine then you need jquery code.
to print gridview

if one button is responsible for all validations and confirmation , it means you need one function and not two
function SaveConfirmation() {
  var Name=$("#txtName").val();
var other=$("#txtOther").val();
if(Name=="" || other=="")
{
return false;
}
    return confirm("Are you sure you want to Save Recordr?");
}

what to do if we have two or more javascript function to load on same button ?

ex. one for text validation
and same for save confirmarion...

see below my button for save record.... i have commented the validation javascript function.....

what to do if i have to use both function on same button....
"btnSave" runat="server" Height="29px" Text="Save" CssClass="buttondesign" Width="65px" OnClientClick="<%--validateForm();--%> if ( ! SaveConfirmation()) return false;" OnClick="btnSave_Click" />
